Universal VFD SHE Lookup Table
A 951-point switching-angle table that covers the full modulation envelope of a 2-level VFD and is compatible with FOC, V/f, and sensorless vector control.
What it is.
A modulation-indexed switching-angle table for two-level Variable Frequency Drives. Drop-in compatible with field-oriented control, V/f scalar control, and sensorless vector control without modifying the regulator.
Produces the same low-distortion output across the full modulation envelope, including the deep-flux-weakening region where carrier-PWM filter sizing usually breaks down. Every row is certifiable against the textbook SHE expansion to machine precision.
Engineered for retrofit teams as well as new designs — there is no solver in the runtime, no neural-network weights, and no licensing call-home. The deliverable is a CSV plus an integration note.
What it does.
- 951 modulation points spanning M = 0.050 through 1.000.
- Avg. 13.3 harmonics eliminated per row, certified against the textbook Fourier expansion.
- FOC, V/f, and sensorless vector compatible — table is regulator-agnostic.
- Standards-aligned with IEEE 519 harmonic limits at the drive output.
- CSV deliverable plus optional firmware-ready C header. No runtime dependency.
Who it is for.
Drive OEMs, motor-control firmware teams, and pump / fan / HVAC integrators that need a single SHE strategy that works across their full speed range — without hand-tuning per operating point.
